i'm new here, i got started on my quest to build a light system when i sold my beloved Philips TV with ambilight for a Samsung 4k that was very lacking in this department. I've been fiddling for a good week or so with different howtos and whatnot. After a lot of trouble and some dabbling with boblight that i got to work 100% for windows (i have a nVidia shield as my "HTPC" and boblight doenst work all that well on it) i got into hyperion. I gotta say i'm over the moon. Got it working with not a lot of trouble.
Got a 269 LED system based on WS2812b leds, and by miracle the RPI2 can actully drive them.
Anyhow, i will at some time rebuild the system to be HDMI based and refine it. When i searched around for parts i came across this splitter. From the minimal testing i have done with it it seems to be 100% what it says.
4k, HDCP 2.2, HDR, HDMI 2.0 (not 2.0a). The price seems very good for such a splitter so I thought I'd tip you fine gentlemen about it.
